Brand: ATORN
Art.-no. 23333110
Manufacturer article no. 21040016
EAN 4050293151008
Application
For high precision centric clamping of drilling, reaming and milling tools.
Execution
- Concentricity tolerance < 0.003 mm
- With axial longitudinal adjustment
- Reducing sleeves for flexible application
- Coolant pressure up to 80 bar
- Temperature-resistant up to 50 °C
Advantage
- Vibration-damping effect reduces micro-cracks and improves workpiece surfaces
- Damping properties increase the service life of the tool and machine spindle
- High torque transfer (dia. 20 = 400 Nm/dia. 32 = 730 Nm)
- All standard shanks can be clamped (dia. tolerance h6)
Notes
The previous standard DIN 69871-1 was replaced by ISO 7388-1.
Delivery
1x SK40 hydraulic expansion chuck (ISO 7388-1)
